Putty network error connection refused raspberry pi

Putty network error connection refused raspberry pi

Re: network error: connection refused

LAN cable to your router, or directly between the Pi and PC?

The «normal» way to connect via SSH is to connect both the PC and Pi to a common network (typically, your home router). Direct Ethernet to Ethernet connections require additional steps, which someone else will have to help you with because I use serial console cables for that.

If you are connecting to your router, and one of the computers is connected by wireless (WiFi), then check your router settings and make sure wireless or AP isolation is off.

Re: network error: connection refused

Did you place the file named «ssh» in the boot partition (first partition on the card) or did use raspbian and placed the file named «ssh» in the folder named «root» (mount point root for the second partition) ?

The «normal » procedure is to mount the memory card on your windows PC where the first partition will be assigned a drive letter. You can use the echo command to create the file named «ssh» on the memory card, if the card is mounted as E:

After a successful boot the file named «ssh» will be deleted.

If you did all this already and you still get «network connection: refused» consider that you will get the same error if you use the ip address of some other system without ssh server. But also pay attention to the previous post concerning client separation if you are using WiFi and wired ethernet.

Re: network error: connection refused

If the card was the NOOBS boot then I do not think putting the SSH file in the root works.

Are you sure you are trying to connect to the Pi IP address? You could try by name raspberrypi.local — I did find I was trying the SSH into the machine I was on the other day by address.

Putty network error connection refused raspberry pi

Just started to play with Rasberry Pi, I was trying to use my laptop as display/input using ssh, I followed this guide http://pihw.wordpress.com/guides/direct . onnection/. I have manage to ping my Rasberry Pi.

However, I have encountered an error «network error: connection refused». From what I have gathered it seems like this is a common problem and have popped in this forum before, I apologies for making a redundant post in advance, but in the previous post I can not find a solution, being a newbie probably made it harder as well.

Further details, I nether have a monitor and keyboard(cough*desk space) to setup my rasberry pi and I am using a windows 8.1 laptop.

Re: Putty network error: connection refused

Re: Putty network error: connection refused

The problem is that if you can’t connect a keyboard and a monitor to the raspberry, we can’t check if the ssh server is running.

It would just be enough to do «sudo raspi-config» from shell and set the ssh server to run at boot and then it should work

Re: Putty network error: connection refused

As far as I’m aware ssh daemon service is usually enabled by default, the likely reason for connection refusal is that your network link hasn’t been correctly setup.
Without a TV or keyboard connected to your Pi I really don’t see how it’s possible to diagnose the problem.

Putty network error connection refused raspberry pi

Hello guys! I have been using my RPi through PuTTY in my laptop then recently I took a break from my Pi project and when I came back today and tried to connect, I got the Connection Refused error. This hasn’t happened before, and I tried pinging to check my ethernet cable, it can ping — even changed another cable to confirm, still nothing.

Any way to get it back to work without reinstalling?

Re: PuTTY: Network Error: Connection Refused

Re: PuTTY: Network Error: Connection Refused

Re: PuTTY: Network Error: Connection Refused

So you have console access to the RPi? What can you ping? The internet router? A well known site on the internet? The laptop?

Presumably if you’ve come back to the RPi after a while you will have rebooted it recently?

REinstalling seems like a drastic measure to solve what might be a simple problem.

Re: PuTTY: Network Error: Connection Refused

I am running the Pi now with a monitor, keyboard and mouse. Pi is connected on LAN to my laptop, it can ping each other.

BTW, I tried changing the ip address of my Pi to another static ip. It fixed the problem, I am able to connect thru PuTTY now, but I want my old ip address back because the codes in my program (esp. Python-MySQL) were assigned to the old ip address.

AND If I change the code to the new ip address now, what are preventive measures so that this won’t happen again? because my project involves in the RPi being headless (used for a store), with the laptop as the server.. I can’t even configure it in the future if I cannot connect to PuTTY

Re: PuTTY: Network Error: Connection Refused

Laptop: 192.168.1.47
Pi: 192.168.1.36
netmask: 255.255.255.0

I can connect using those since late November, but just today, got the error. I changed my Pi’s ip to 192.168.1.37 and I was able to connect again (and changed back to 192.168.1.36 and the error comes back. lol)

Re: PuTTY: Network Error: Connection Refused

I suggested: «The address you used previously might have been re-assigned to another device on the network.»

Looks like that might be the case?

Re: PuTTY: Network Error: Connection Refused

It’s the DHCP server on your router that hands out all of the IP addresses (unless you do something on the requesting machine to set a static address). Each one has a lease time after which it must be renewed or it’s available for some other machine to use.

Anything that runs as a server; that’s printers, web servers, raspberry pis, routers, WiFi access points, etc. should be configured with a static IP address that is NOT in the range of your DHCP pool. On my network addresses xxx.xxx.xxx.1 to xxx.xxx.xxx.29 are used for fixed, xxx.xxx.xxx.30 to xxx.xxx.xxx.99 are DHCP, xxx.xxx.xxx.100 is used by the router, xxx.xxx.xxx.200 to xxx.xxx.xxx.253 are used for networking equipment. xxx.xxx.xxx.254 is the gateway.

My Technicolor router allows me to assign fixed IP addresses. If it didn’t I’d hard code the address in /etc/network/interfaces.

Putty network error connection refused raspberry pi

I recently bought Raspberry Pi 3 but I am unable to login I am getting an error as ‘network error: connection refused’. I searched before posting it here but still could not fix the issue. I am trying log-in Raspberry Pi using my windows 7 laptop since I do not have a display and keyboard.

I did following:
1) Burnt raspbian image to SD card and inserted to Rpi
2) Connected Ethernet cable to internet router (I am able see green led blinking)
3) Used advanced scanner to find Rpi IP to perform SSH using Putty
4) Putty gives error ‘network error connection refused’

I tried following troubleshooting:
1) Re-verified Rpi Ip using Kitty tool as well and it is same
2) Used my other windows 7 PC, still same error
3) Turned off windows fire-wall
4) Restarted my router

Please suggest what else need to check, to resolve this issue.

Re: Network Error: Connection Refused

Re: Network Error: Connection Refused

As Trev has pointed out it is because SSH is disabled by default in the newer Raspbian images.

Create a blank text file called «ssh» on the root of the SD card using your laptop. Then boot the Pi from it. That will enable SSH.

Re: Network Error: Connection Refused

Re: Network Error: Connection Refused

Even i am getting the network saying connection refused while trying to connect to raspberry pi via putty and ssh form laptop. i have tried all the methods and i am failed, the above method also i followed but dint work.

I suspect that windows firewall is preventing the SSH connections. Please help me with this problem, i am trying to debug this issue from past one month and failing every time.

Thanks in advance,
Nagaraj

RPI3 Raspbian GNU/Linux 8 (jessie)Linux 4.9.50-v7+ #1035 SMP with RSA KEY

After sudo apt-get update && sudo apt-get dist-upgrade I configured OpenVPN (with www.vpn.io) . everything worked with new fiber router . also worked (installed 6 months ago) SSH with RSA KEY.
Then I installed a Fritz! Box 7490 as a cascaded router on fiber modem (192.168.1.1) and strangely RPi kept IP assigned by the fiber modem even if the Fritz! 7490 LAN works on a separate network (192.168.178.1).
I solved this problem by setting static IP on Rpi
with sudo nano /etc/dhcpcd.conf
At the bottom of the file I entered:
nohook lookup-hostname
nodhcp
interface eth0
static ip_address=192.168.178.32/24
static routers=192.168.178.1
static domain_name_servers=192.168.178.1

Now the RPI can also be reached with PING in LAN but SSH does not even work in Lan (and not even in wan).
# SSH enabled, SSH port enabled
# RSA KEY the usual installed 6 months ago (with fiber router worked)
# Rpi reachable with ping in lan

PROBLEM — with sudo systemctl status ssh.service
i see:
● ssh.service — OpenBSD Secure Shell server

Can I go back and restore the old configuration? befor sudo apt-get update && sudo apt-get dist-upgrade .
How .
Thank you

Re: Network Error: Connection Refused

I also tried with these commands but nothing changed:
sudo service ssh restart

sudo rm /etc/ssh/ssh_host_* && sudo dpkg-reconfigure openssh-server

With sudo sshd -T i see:
/etc/ssh/sshd_config: line 93: Bad configuration option: AuthorizedKeysFiles
/etc/ssh/sshd_config: terminating, 1 bad configuration options

Line 93 is this: AuthorizedKeysFiles .ssh/authorized_keys
the file exists

Headless SSH on Raspberry Pi3B: connection refused

Thanks for taking the time and helping me out.

Heedlessly ssh into a Raspberry Pi 3B on my Win7 platform(s).

I have two Raspberry Pi 2 B’s that I have set up in the past with no issues incl headless setup. I have a new Raspberry Pi 3B and cannot ssh into it at all. I have followed the exact same steps I have for my Pi 2B’s with exception to the image.

What I have done so far:

Download the latest Raspbian Jessie Image and format the Sd card using Win32DiskImager.

Power up the Raspberry

Ping the raspberry successfully using the Pi’s IP address.

Open Putty and enter the IP on port 22 (not that the port should matter)

At this point when I try click «Open» after having entered the Pi’s IP address I get the following error: «Connection Refused»

I then used a Screen and keyboard to boot the Pi 3B. Once booted I opened terminal and entered «sudo raspi-config», where I then enabled SSH manually.

I unplugged everything from the Pi3, plugged the LAN cable back into my laptop and Pi3 and powered up the Pi3B.

I could still ping the Pi

Using Putty and the Pi3B’s IP address I then clicked «open» and the following error came up: «Network Error: Software cause connection abort»

I have now also added a router to the setup, checked up what the ip of the pi is through the router and tried connecting with putty onto the pi, but I still get «Network Error: Connection Refused»

I am running out of ideas, any help would be appreciated. Thank you Misha

After comically large amounts of googling and hassle I found a solution here: https://www.raspberrypi.org/blog/a-security-update-for-raspbian-pixel/

With the RPi3B and 11-01-2017 Raspbian Jessie combo (I dont know with which one the issue lies) one has to add a blank file named «ssh» into the boot directory of the SD card. This can be done on your Windows platform. Ensure that the file has no file extensions, because if it has any file extensions it wont work. Good practice anyway to have your file extensions showing in any case.

Hope this helps anyone else.

I have followed the exact same steps I have for my Pi 2B’s.

What you didn’t do is read the release notes of all the raspbian versions between your old and new image before following those steps. In one of them it says that you have to put a file (can be empty) with name ssh in the boot partition. Upon first boot ssh will be enabled and the file removed.

(Don’t do what I did. I put the file ‘ssh’ in the boot directory of the main partition, but that turned out to be the mount point for the (small) boot partition, hiding the file ‘ssh’ at mount and rendering the whole exercise without effect. It took me some time before I found my mistake. You have to put the file in the small boot partition itself.)
